4 Claims.

Our 4invention relates to the distributor member for stokers of. the type wherein a conduit communicates with the ring opening of a boiler rebox. As the invention appertains to the distributor member and its associated parts, only so much of the remainder of the stoker mechanism is shown as is necessary to indicate the relation of the parts.

It is the object of the invention to provide an improved and novel construction whereby the distributor member can be easily and readily removed from its position. Other objects of the invention reside in the specific form of the parts and in the particular means employed to hold the distributor member in place.

On the drawing,

Figure 1 is a detail vertical section through the upright wall of a boiler rebox showing the device of the invention applied thereto in similar section;

Figure 2 is a plan view of the structure of Figure 1 with the boiler rebox shown in transverse cross section;

Figure 3 is a fragmentary sectional view taken on the line 3 3 of. Figure l; and

Figure 4 is a fragmentary sectional View taken on the line 4 4 of Figure 1.

Referring to the drawing, there is shown at I0 a portion of an upstanding wall of a boiler rebox having a firing opening II therein to which fuel is advanced by the screw I2 housed within the inclined Stoker conduit I3 which opens endwise into the firing opening. The rectangular mouth portion I4 of the conduit extends entirely across the lower portion of the firing opening slightly above the lower marginal edge thereof to provide a space I5 between the bottom wall I6 of the conduit and that portion of the ilrebox wall forming the lower extremity of the firing opening.

Bolts I'I engaging the flanges I8 at the sides of the mouth portion I4 with the firebox wall I0 secure the conduit to the rebox in endwise communication with the ring opening. Fuel advanced by the screw I2 passes along the bottom wall I6 onto the chambered distributor or jet member I9 positioned in the firing opening. This jet member constitutes an extension of the bottom wall or floor I6 of. the conduit and is separable therefrom. It extends from one side of the ring opening to the other and includes an upstanding front wall 2II having vertically and laterally spaced radially directed jet openings 2| communicating with the cored chambers 22, 23 for discharging pressure fluid fuel propelling blasts over and above the distributing plate 24.

(Cl. 11G-101) Pressure fluid is supplied to the chambers 22, 23 by supply lines 25 extending rearwardly from the jet member through the space I5 to a source of supply exterior of the rebox.

Any suitable means may be used for fastening 5 the distributing plate 24 to the jet member I9 but for purposes of illustration the plate is shown as secured to the jet member by the countersunk cap screws 26 threaded into the ledge 2'I of the jet member.

Preferably, the floor I 6 terminates in the plane of the outside surface of the iirebox Wall I0 and the conduit side walls 28 extend into the firing opening slightly beyond said plane. As best shown in Figure 4, the extended portions o-f the side walls contact the rounded edges of the firebox wall at the firing opening to prevent loss of fuel through the gaps 30. The rear end of the jet member I9 abuts the front end of the floor I6 and the top of the jet member lies in 20 the same inclined plane as the oor. As shown the jet member I9 is almost wholly within the confines of the ring opening although in some instances it may be desirable to position the front wall 20 at or beyond the inside surface of the rebox wall I0.

An improved construction is provided for supporting the jet member I9. For this purpose the jet member is formed at its sides with downwardly opening grooves or sockets 3| which are 'adapted to slide downwardly over pins 32 extending toward each other from the opposite side portions 33 of the rebox wall forming the sides of the ring opening Il. Preferably a pair of longitudinally and vertically spaced pins and sockets positioned below the level of the fuel supporting surface of the jet member at opposite sides thereof are employed. 'Ihis construction firmly supports the jet member and prevents it from tilting or tipping over. However, the foremost pin and socket only at each side can be used, inasmuch as the contacting ends of the jet member and the conduit floor will prevent tipping or tilting of the jet member. The latter hangs, as it were, by its own weight on the pins and the spacing of the pins in different levels and the sockets having their axes at an angle to the top surface of the jet member overcomes any tendency of the upward movement of the fuel to raise the jet member. 50

When for any reason it is necessary to remove the jet member it may be readily removed and replaced by rst disconnecting the supply lines 25 and then raising the jet member upwardly in the ming opening to clear the pins 32. This can be done without disturbing the setting of the conduit and without dumping the fire, inasmuch as the entire operation takes place in the ring opening. The jet member can be withdrawn from the iirebox through that portion of the firing opening above the conduit, which portion, as usual, is provided for hand ring and is normally closed by the redoor 35.

We claim:

1. In combination, a rebox having an upstanding Wall with a firing opening therein, a distributor member in said firing opening, and means for supporting said member from the rebox wall comprising pins extending toward each other from the opposite side portions of the firebox wall forming the sides of the ring opening and downwardly opening grooves in the adjacent ends of said member receiving said pins.

2. In combination, a rebox having an upstanding wall with a ring opening therein, a distributor member in said iiring opening, and means for supporting said member from the rebox wall comprising pins extending toward each other from the opposite portions of the rebox wall forming the sides of the ring opening, each of said side portions having a plurality of such pins, and a plurality of downwardly opening grooves in each of the adjacent ends of said member receiving said pins.

3. In combination, a rebox having an upstanding wall with a iiring opening therein, a conduit exterior of the rebox communicating with the ring opening, a distributor member in said ring opening constituting an extension of the conduit, and means for supporting said member from the firebox wall comprising pins extending toward each other from the opposite side portions of the rebox wall forming the sides of the ring opening and downwardly opening grooves in the adjacent ends of said member receiving said pins.

4. In combination, a rebox having an up- Standing Wall with a ring opening therein, a conduit exterior of the firebox communicating with the ring opening, a distributor member in said ring opening constituting an extension of the conduit, and means for supporting said member from the iirebox wall comprising pins extending toward each other from the opposite side portions of the rebox wall forming the sides of the firing opening, each of said side portions having a plurality of such pins, and a plurality of downwardly opening grooves in each of the adjacent ends of said member receiving said pins.
